I am currently working on a commercial GIS project and have a lot of uncertainties regarding legal situations and terms of use for different maps.
For example, the data of eurostat does not allow a commercial use of this data. But looking at the following dataset by the European Environment Agency, you can see, that they used the eurosat data as template. According to their terms of use, the data is also free for commercial use.
Now I am asking myself whether I could also use some datasets, which are not free for commercial use, redraw them in GIS for myself based on the template and then work with them without violating any legal rights?
